摘　　要：在微生物浸出体系中加入YW-200形成的新的浸矿体系,对铜矿石中伴生银的浸出进行试验,在实验室柱浸条件下,5个月银浸出率80.46%(-5mm粒度)和67.87%(-20mm粒度),说明YW-200浸矿体系能较好地浸出铜矿中的伴生银,且对铜的浸出没有不良影响,同时阐述了浸矿过程中的几个影响因素。The leaching experiment of associated silver in copper ore is carried in laboratoty condition. The leaching system consists of bio-leaching with YW-200. After leaching for five months, the leaching recovery for silver re, ached 80.46% （for size of-5mm） and 67.87% （for size of-20mm）. It proved the YW-200 system can be used for recovery of silver from copper ore and without negative effect to the leaching of copper. Some influential factors in leaching process are explained.
